INA332 INA2332 SBOS216B – SEPTEMBER 2001 - REVISED OCTOBER 2006 www.ti.com DESCRIPTION The INA332 and INA2332 are rail-to-rail output, low-power CMOS instrumentation amplifiers that offer wide range, single- supply, and bipolar-supply operation. Using a special manu- facturing flow, the INA332 family provides the lowest cost available, while still achieving low-noise amplification of dif- ferential signals with low quiescent current of 415 µ A (drop- ping to 0.01 µ A when shut down). Returning to normal opera- tion within microseconds, this INA can be used for battery or multichannel applications. Configured internally in a gain of 5V/V, the INA332 offers flexibility in higher gains by choosing external resistors. FEATURES DESIGNED FOR LOW COST HIGH GAIN ACCURACY: G = 5, 0.07%, 2ppm/ ° C GAIN SET WITH EXT. RESISTORS FOR > 5V/V HIGH CMRR: 73dB DC, 50dB at 45kHz LOW BIAS CURRENT: 0.5pA BANDWIDTH, SLEW RATE: 2.0MHz, 5V/ µ s RAIL-TO-RAIL OUTPUT SWING: (V+) – 0.02V WIDE TEMPERATURE RANGE: –55 ° C to +125 ° C LOW QUIESCENT CURRENT: 490 µ A max/chan SHUTDOWN: 0.01 µ A MSOP-8 SINGLE AND TSSOP-14 DUAL PACKAGES Copyright © 2001-2006, Texas Instruments Incorporated Low-Power, Single-Supply, CMOS INSTRUMENTATION AMPLIFIERS APPLICATIONS INDUSTRIAL SENSOR AMPLIFIERS: Bridge, RTD, Thermocouple, Position PHYSIOLOGICAL AMPLIFIERS: ECG, EEG, EMG A/D CONVERTER SIGNAL CONDITIONING DIFFERENTIAL LINE RECEIVERS WITH GAIN FIELD UTILITY METERS PCMCIA CARDS AUDIO AMPLIFIERS COMMUNICATION SYSTEMS TEST EQUIPMENT AUTOMOTIVE INSTRUMENTATION The INA332 rejects line noise and its harmonics because common-mode error remains low even at higher frequencies. High bandwidth and slew rate make the INA332 ideal for directly driving sampling Analog-to-Digital (A/D) converters as well as general-purpose applications. With high precision, low cost, and small packages, the INA332 outperforms discrete designs. Additionally, because they are specified for a wide tempera- ture range of –55 ° C to +125 ° C, the INA332 family can be used in demanding environments.
